WILLIAM VAN ANDEN, OF POUGHKEEPSIE, NEW YORK.

MACHINERY FOR MAKING RAILROAD-CHAIRS.

Specification of Letters Patent No. 9,906, dated August 2, 1853.

To all whom it may concern:

Be it known that I, WILLIAM VAN ANDEN, of Poughkeepsie, Dutchess county,State of New York, have invented certain new and useful Improvements inMachinery for Making Railroad-Chairs; and I do hereby declare thefollowing to be a full description of the same.

The nature of my invention consists in arranging and combining with asuitable frame a shaft propelled by any convenient power, on which issecured a cam for operating a lever for depressing the die for holdingthe metal while being cut by a pair of roller shears, which are forcedupward by a second lever, operated by a second cam also on the drivingshaft, the operation of the rollers being to cut the grain of the metalmore perfectly than by a fixed or punching cutting arrangement, also incombination with the said roller shears, two adjustable binders, securedat each side of the machine on the ends of levers, operated by cams onthe ends of the driving shafts, for the purpose of binding over the lipsof the chair as they are cut and raised by the action of the rollershears, so as to give them the form of the die, from which the chair isdischarged by a forked rod on the end of a connecting rod working on themain or driving shaft and projected out by a cam on the driving shaft asthe shears, binders and die are restored to their original to push thechair off the head of the die, and projected back again by a second camon the opposite side of the driving shaft for that purpose. But todescribe my invention more particularly I will refer to the accompanyingdrawings forming a part of this schedule, the same letters wherever theyoccur referring to the same parts.

Figure 1 is a view of the front elevation of the machine. Fig. 2 is aview of the side elevation of the machine. Fig. 3 is a view of the backelevation of the machine. Fig. 4: is a cut section of the machinethrough the red line 00, m, Fig. 5. Fig. 5 is a plan view of themachine. Fig. 6 is a detached view of the roller shears and dies. Fig. 7is a detached view of the discharging rod and cams as arranged on themain shaft for operating it. Fig. 8 is a detached view of the lever foroperating the upper die and cam on the main shaft for working the same.

Letter A, is the frame of the machine and is made of iron or othermaterial, as

may be desired. On the front of the frame is a box or slide way B, inwhich the shear stock C, works. In the head of the shear stock issecured at each side shear holders D, D. These shear holders work indovetails cut in the shear stock. so as to admit of the shears beingadjusted out or in, as may be required for various kinds of work.Between ear pieces in these shear holders are arranged roller shears E,E. The use of these rollers in the operation of cutting railroad chairsfrom wrought iron is very important and constitute a very essential partof my invention. By the use of rollers in cutting the lips of the chairthe grain of the metal is not drawn, as would be the case in using adevice analogous to punching, and at the same time less power isrequired in the operation.

Letter F, is a lever for operating the shear stock and shears. Thislever has a fulcrum G, at the back side of the front of the frame, andis bent or curved up at the back end, so as to be operated upon by a camH, on the driving shaft I, so that as the toe of the cam depresses theback end of the lever the front end, working in a slot J, in the shearstock, raises it to cut the meta held by the dies K, and L.

Letter K is the lower half of the die, and is stationary, being firmlysecured to the face of the frame, so as to resist the pressure of theupper and movable half of the die L, which is secured in a stock M,working in a case or box N, secured to the front of the machine, at theupper side, similar to the case for holding the shear stock at the lowerside of the front of the frame. The movable half of the die L, is madeso as to have a certain amount of motion in the stock vertically, andfor that purpose slots 10., n, are cut in the die stock, to sustain themovable die by means of a pin 79, passing through the die L. The objectof this motion is to allow the head of the die to drop down, as thestock is being lifted, after the chair has been bent on it, for thedischarger O, to be proj ected out to discharge the chair preparatory tothe next revolution of the machine. This die and the stock in which itis secured is operated by a lever P, having a fulcrum Q, at the upperand back side of the front of the machine, and is curved or bent down atthe back end, so as to be operated by a quadrant shaped cam R, on thedriving shaft 1, which by means of a collar .9, attached to the end ofthe lever P, and working on the driving shaft I, also operates to liftthe die stock after the chair has been formed.

Letters T, T, are the 'benders, which are arranged by means of adjustingscrews 6, t and t, t, in stocks U, U, working in slides V, V, secured tothe front of the machine at an oblique angle, so as to press from abovedownward to bend the lip of the chair perfectly down upon the die. Thesebenders are operated by means of levers W, W, secured by fulcra X, X, tothe sides of the machine frame and having their back ends working inchannel ways in cams 1 g, on the ends of the driving shaft I. Theoperation of these cams is to give an outward and lifting motion to theback ends of the bender levers, so as to operate the benders in theright direction for the purposes required, and withdraw them in time forthe action 'of the discharger rod 0. This discharger at the front end isforked and shaped so as to fit the sides of the movable die as it isprojected out to discharge the chair. The back end of the discharger isattached to a collar piece 0 surrounding the driving shaft I, on whichare two cams 2, 2 which alternately act on the collar to project thedischarger out to remove the chair from the die and withdraw it againbefore the down stroke of the die takes place again.

The operation of my machine is that when the piece of iron is preparedfor forming the chair it is placed upon the fixed half of the die, (tofacilitate which guides will be used in a working machine,) when therotation of the driving shaft by means of the quadrant shaped cam R, andlever P, forces down the upper half of the die L, upon the plate ofiron. While this is being done the cam H, on the driving shaft depressesthe end of the lever F, and raises at the front end the shear stock androller shears to cut and bend up the lip of the chair, which having beendone the cam H, having passed its greatest diameter lets the shears dropin time to allow the cams 1 12 on the ends of the driving shaft, throughthe levers W, W, to force in the benders to complete the operation ofcutting and bending the wrought iron chair. When this is done the cams 11 draw back the benders, and the quadrant shaped cam R, acting upon thelower side of the collar on the end of the lever P, lifts the stock ofthe upper half of the die, which dropping down in the slot in the stockallows the cam Z, on the driving shaft to project the discharging rod 0,forward to discharge the chair oif the die, when the cam Z comes intoaction and withdraws the discharger again and the machine is then readyfor a repetition of the operation.

Having now described my invention and its operation I will proceed tostate what I claim and desire to secure by Letters Patent of the UnitedStates.

WVha-t I claim is- 1. The combination of rollers with adjustable shearstocks for cutting and shaping the lips of wrought iron rail roadchairs, substantially as hereinbefore set forth, and their combinationwith the dies for that purpose.

2. I also claim the use of a movable drop upper half, or female die, incombination with a stock substantially set forth, and their combinationwith the discharging apparatus operated substantially as hereinbeforeset forth.

3. I also claim the use of adjustable and removable benders, in benderstocks, in combination with the levers and cams on the main shaft foroperating the same in an oblique and downward direction, and theircombination with the dies and cutters for making wrought iron rail roadchairs.
